How about become a subsea worker? Either ROV or diving personnel?

Sat divers earn more than a thousand dollar US per day. Work for a month job place you in a 6 figure income group already.

Why become an engineer (especially you, office based engineer)? As when you come on board you are the cheapest labour there. 3,000 MYR a month? Oh man.

EDIT: Oh because you love engineering but not that keen to actually DO STUFF in the water (but you took subsea engineering WTF), how about get a CSWIP 3.4u ticket (4,XXX USD for the course and exams), and land yourself a 700-1,000 USD per day career.

With a month job pay, you can pay the argentum dei of an apartment in KL. Or buy a Ducati in CASH.

Oh you said sales line also make this kind of money? Of course but that's not SUBSEA.

Still better than your measly 3,000 MYR. PERIOD.
